Why are dry-type transformers more popular? Where can they be used?

2025,06,18

In modern power systems, transformers are indispensable key equipment, and dry-type transformers have gradually become the mainstream choice in the market due to their safety, environmental protection, and high efficiency. Compared with traditional oil-immersed transformers, dry-type transformers show stronger adaptability in multiple application scenarios.

So, why are dry-type transformers more popular? What occasions are they suitable for? Hubei Jutai will give you a detailed analysis.

Advantages of dry-type transformers

1. Safe and reliable, no fire hazards

Traditional oil transformers use insulating oil as cooling and insulating medium. Once leakage or short circuit occurs, it may cause fire or explosion risks. Dry-type Power Transformers use epoxy resin or air insulation, no oil medium is required, which fundamentally eliminates oil pollution and combustion risks. They are particularly suitable for places with high safety requirements, such as high-rise buildings, subways, hospitals, etc.

2. Environmental protection and energy saving, in line with the trend of green development

Dry-type transformers do not use insulating oil, which avoids the pollution of the environment by oil leakage, and meets modern environmental protection requirements. At the same time, its operating loss is low, energy efficiency is high, and long-term use can reduce electricity costs, which is in line with national energy conservation and emission reduction policies.

3. Maintenance-free and long service life

Oil-immersed transformers need to check the oil level and oil quality regularly, and the maintenance cost is high. The dry-type three-phase transformer has a simple structure and does not require oil maintenance, which reduces the workload of operation and maintenance, extends the life of the equipment, and reduces the overall cost.

4. Strong adaptability and flexible installation

Dry-type transformers are relatively small in size and can adapt to different installation environments, such as indoors, basements, small spaces, etc. At the same time, it has good moisture and dust resistance, and is suitable for harsh environments such as damp and dusty.

Application scenarios of dry-type transformers

1. Commercial buildings and public facilities

In crowded places such as shopping malls, office buildings, hotels, and hospitals, safety is the primary consideration. Dry-type transformers are the preferred power distribution equipment in these places because of their oil-free and fireproof characteristics.

2. Industrial manufacturing and mining

Factories, mines and other environments may have dust, high temperature, and corrosive gases. Traditional oil transformers are easily affected by the environment, while dry-type transformers are highly weather-resistant and can operate stably under complex working conditions.

3. Rail transit and airports

Transportation hubs such as subways, high-speed railways, and airports have extremely high requirements for the reliability of power equipment. Dry-type transformers are widely used in such key infrastructures due to their high safety and maintenance-free characteristics.

4. New energy power generation and substations

In new energy fields such as wind power generation and photovoltaic power stations, dry-type transformers have become an ideal choice for supporting power equipment because of their high efficiency, energy saving, and strong adaptability.
